Abstract

PURPOSE: To shorten stopping time at the time of maintenance and facilitate a exchange of a rim with teeth by clamping the rim with teeth which is formed as a separate unit and is constituted of two parts by a pair of removable hub members. CONSTITUTION: This chain wheel is assembled by holding a rim with teeth 3 which is constituted of parts 3a, 3b between internal and external hub members 1, 2, interposing a reinforcing disc 4 and fastening the disc 4 with a bolt 7. By this constitution, because the rim with teeth 3 can be easily removed and exchanged if the bolt 7 is removed, a change in the number of teeth can be easily performed and the stopping time can be shortened.

ルト７によって互に締結されている。The chainwheel of the present invention is constructed from standard parts and assembled in a variety of ways to provide different types of chainwheels. A standard wheel with one toothed rim has two inner and outer hub parts 1, 2, a toothed rim 3 divided into two parts 3a; 3b, and a reinforcing disc 4. The hub members 1 and 2 and the toothed rim 3 are
For example, it is made of plastic material such as nylon,
On the other hand, the reinforcing disk 4 is made of steel. The reinforcing disk 4 is installed on the drive shaft 5 and is connected to the drive shaft 5 by a key in a keyway 6. The hub part 1.2, the parts 3a, 3b of the toothed rim and the reinforcing disc 4 are fastened together by bolts 7.

とができる。The two parts 3a, 3b of the toothed rim are connected to the hub part 1.2.
By engaging the trapezoidal recess 8 provided on the inner surface of the member with the trapezoidal protrusions 9 of the members 3a, 3b provided in corresponding positions, the member 3a, 3b is held in its normal position. The trapezoidal recess 8 functions not only as a positioning guide but also as a friction surface between the hub member and the toothed rim. This is tooth 4
=j The rim 3 is not directly connected to the drive shaft 5, and the drive shaft 5
This is because the driving force is transmitted to the toothed rim 3 via the reinforcing disk 4 and the hub members 1 and 2. Therefore, the above-mentioned members are fastened with a large force so that the frictional resistance is sufficiently greater than the transmission torque of the drive shaft 5. Furthermore, by changing the fastening force, the maximum torque transmitted to the toothed rim 3 can be set, thereby preventing overload on the conveyor chain and ensuring safety.

化を図れる。When the toothed rim 3 is damaged or when the toothed rim 3 is replaced because the number of teeth needs to be changed, the two parts 3a of the toothed rim can be separated by loosening the bolt 7 and separating the hub members 1 and 2. , 3b
can be removed from the hub member and replaced with a new one. This is possible even if only one of the parts 3a, 3b needs to be replaced. The bolt 7 is then fastened with a force corresponding to a predetermined frictional resistance. Thus, the toothed rim can be replaced without removing the hub member from the drive shaft, reducing working time and the number of replacement parts.

It is also possible to provide a double chain wheel by providing two inner hub members 2 inside two outer hub members 1 and two toothed rims 3 between them. Furthermore,
It is also possible to form a triple chain wheel by providing four inner hub members 2 inside two outer hub members 1 and three toothed rims 3 between them.
